python停用词表 更新热词表

Python停用词表更新,现在包含了最新的热门词汇。这些词汇在文本分析中可能会影响结果的准确性,因此需要被排除在外。

1. 获取停用词表

我们需要从网上下载一个中文停用词表,这里我们使用jieba库的内置停用词表。

import jieba
获取停用词表
stopwords = set(jieba.analyse.stop_words)

2. 读取文本数据

我们需要读取文本数据,这里我们假设文本数据存储在一个名为text_data.txt的文件中。

with open('text_data.txt', 'r', encoding='utf8') as f:
    text = f.read()

3. 分词并去除停用词

使用jieba库对文本进行分词,并去除停用词。

import jieba.posseg as pseg
分词并去除停用词
words = [word for word, flag in pseg.cut(text) if word not in stopwords]

4. 统计词频

使用collections库中的Counter类统计词频。

from collections import Counter
统计词频
word_freq = Counter(words)

5. 更新热词表

将统计出的词频按照降序排列,取前N个作为热词。

更新热词表
hotwords = word_freq.most_common(N)

6. 输出热词表

将热词表输出到文件。

输出热词表
with open('hotwords.txt', 'w', encoding='utf8') as f:
    for word, freq in hotwords:
        f.write(f'{word}: {freq}
')

至此,我们已经完成了Python停用词表的更新热词表操作。

请注意,停用词表是英文的,而更新热词表是中文的,这个介绍仅作为示例,实际上停用词表和热词表的内容可以根据实际需求进行调整,停用词表通常包含一些常见的、没有实际意义的单词,而热词表则包含当前热门的话题或关键词。
